Learn creative coding writing simple programs

Now we use the sin() function to control many different properties. We animate circles moving on the screen. Their X and Y position is calculated using the sine function. The size, hue and brightness of each circle is also calculated with different formulas that use sin(). This trigonometric function by default gives a very simple and predictable result. But when we combine multiple sin() calls we can get more complex graphics, but which still change in a smooth way.

To indicate that a word in your comment is code,
use the `backtick`. Example Do `float` and `int` smell similar?
To highlight code blocks, use ```processing and ``` like this:
